So because the server has grown to be an international server I thought we could have an extra option. When I talk to a player I never know what language he speaks or from what country he is.
The command is this one: /set country [Germany] and your nick would then appear like this :

[GER] Stone Mike_

And it would work with a lot of countries/languages. So you would always know to who you'r talking to. Ofcourse you could also not set any country and you would appear normal.

(If you look, "Germany" has come up with "GER", meaning that it wouldn't output exactly what the user put in, but rather the shorter version, so putting in something inappropriate would come up as nothing)
